[OZAPRS] Changes to VKAPRS-IS server configuration

[Merv Joyce]

Geoff,

Thanks for the update information.

It would appear that "aprsd" does not support passing forward Tier2
filters.  Looks like I'm stuck with using the pre-deined filter ports
(eg 14577 for local stations).  From your message I assume that only
port 14580 is standardised, so using port 14577 with rotate.aprs2.net
might be unpredictable.  I have set my one and only "server" to
"first.aprs.net.au".

Any comment from other "aprsd" users

Folks,

 

This is a heads up that there will be some changes being made to the
setup of the VKAPRS-IS servers over the next couple of days.  

 

Currently we have TWO servers, both members of the TIER2 REGIONAL server
cluster.  

Servers within the TIER2 cluster connect to the T2CORE servers, which in
turn connect to the three APRS CORE servers in the US.  The FINDU
servers are connected to the APRS CORE.

 

The change to our setup will be that the current T2AUST server
(first.aprs.net.au) will be upgraded to T2CORE status to provide
improved connectivity to the APRS core from our region.  The result of
this will be that this server will only accept connections from the
TIER2 REGIONAL servers.  Second.aprs.net.au (T2AUST-2) will become
first.aprs.net.au (T2AUST), and will be capable of handling all
connections from I-Gates and users.

 

A Reminder here that the recommendation for client connections to the
TIER2 servers is to use port 14580, and define your required filter
settings in the connect string.  This would allow your client to use the
special URL "rotate.aprs2.net", which is set up to rotate connections
between all 31 available TIER2 servers.  (EVERY TIER2 server has an
identical configuration for port 14580)  

 

This change will also remove the current security problem with
"first.aprs.net.au" where users were being added to the systems firewall
and being blocked due to false triggering of the Intrusion Detection
system (this IDS is not implemented on the current 'second' box)

 

This change should be completely transparent to clients - this is simply
an update as to what is going on in the network.
